Fine-tuned DistilBERT Model for Indonesian Text Classification

Overview

This repository contains a fine-tuned version of the DistilBERT model (based on cahya/distilbert-base-indonesian) for Indonesian text classification. The model is trained to classify text into eight distinct categories, including politics, socio-cultural, defense and security, ideology, economy, natural resources, demography, and geography.

Dataset

The dataset used for training the model underwent significant augmentation and balancing to address class imbalance issues. Below are the details of the dataset before and after augmentation:

Usage

To use this model, you can load it using the Hugging Face Transformers library:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-classification", model="Rendika/Trained-DistilBERT-Indonesia-Presidential-Election-Balanced-Dataset")

# Load model directly
from transformers import AutoTokenizer, AutoModelForSequenceClassification

tokenizer = AutoTokenizer.from_pretrained("Rendika/Trained-DistilBERT-Indonesia-Presidential-Election-Balanced-Dataset")
model = AutoModelForSequenceClassification.from_pretrained("Rendika/Trained-DistilBERT-Indonesia-Presidential-Election-Balanced-Dataset")

Conclusion

This fine-tuned DistilBERT model for Indonesian text classification demonstrates robust performance across various categories. The augmentation and balancing of the dataset have contributed significantly to the model's ability to generalize well on the test set.

Feel free to use this model for your Indonesian text classification tasks, and don't hesitate to reach out if you have any questions or feedback.
